Referring to the drawings, Fig. 1 illustrates a conventional type ofwinding machine comprising certain essential elements which are wellknown in the art. The operating parts of the machine are mounted on abox-like frame 2 carrying bearings for a horizontal windingspindle 3 anda parallel cam-shaft 4 arranged therebelow. The winding-spindle 3overhangs the forward side of the frame 2' and carries a suitable formof cop-holder 5, herein illustrated in the shape of a truncated cone,for receiving the paper cop-tube C or other yarn-receiver, for example,a wooden cone, on which the conical package is wound. Thewinding-spindle 3 is driven from suitable power-operated means such as abelt-pulley 6 connected to the spindle by a clutch 7. The cam-shaft 4 isdriven from the spindle 3 by a train of gearing 8 enclosed in a case orhousing 9 at one side ofthe frame 2. A pulley 11 on the end of thespindle 3 is connected by a belt 12 to drive -a similar pulley 13 which,through the gearing 8, drivesthe cam-shaft 4 at a reduced rate of speed.85

Mounted fast on the lower shaft 4 is a helically-grooved cam 14 whichactuates the traverse-mechanism, next described, to reciprocate athread-guide 16 to deposit the yarn, thread or other strand material onthe package.

The traverse-mechanism is mounted on a traverse-fra'me 17 constituted bya horizontal bar or member 18 supported by opposite arms 19 and 21 whichare pivoted to rock on the bearings 22 and 23 for the cam-shaft 4. Thetraverse-frame 95 17 is provided with an overhanging portion 24projecting outwardly beyond the arm 19 and forming an extension of itsmain horizontal member 18. The two horizontal members 18 and 24 areprovided with a groove 26, see Fig. 00 2, adapted to serve as a track orguideway for a sliding traverse-rod 2'7. The inner end of thetraverse-rod 27 is connected to a' slide 28 which carries a roller orbowl 29 engaged with the helical groove of the cam 14. The outer end ofthe traverse-rod 27 carries an arm 31 in which is mounted thethread-guide 16 in a manner as next described. The arm 31 is formed atits upper end with a circular opening for receiving the guide 16 whichis of the button type having a 1 slot or groove 33 for the thread, yarnor other strand to draw through.

The outer arm 19 of the traverse-frame 1'7 is extended below its bearinghub, preferably in a separate arm 34 attached thereto and terminating ina counterweight 36 which tends to maintain the traverse-frame insubstantially erect position. Attached to the overhanging part 24 of thetraverse-frame 17 is a plate or back 37 against which the thread-guidearm 31 bears to direct the guide 16 in a course parallel to the surfaceon which the winding is performed. In the .machine herein illustratedthe traverse-frame back 37 has its bearing face 38 inclined at an angleto the axis of the winding-spindle 3 in conformity with the taper of thecone-holder 5, while in other instances the back may extend parallel tothe axis of the winding-spindle when a cylindrical package is to bewound on the machine. Secured upon the traverse-frame back 3'7 byopposite screws 39 is a curved wire thread-bail 40 which extendsparallel with the surface of the cop-tube and along which the strandslides during its traverse. In accordance with the present invention thethread-bail 40 serves to position the strand as it leads to the cop-tubeC so that it will extend across the path of the threadguide 16, wherebythe latter is caused to pick up the strand upon completion of thereserve winding to thereafter traverse the yarn to wind the package.

In the present drawings the machine is illustrated as operating on ayarn strand y drawing off from a supply arranged below, but not hereinshown. The yarn draws upwardly through a tension-device 43 of anysuitable construction, thence through a slub-catcher 44 and leads acrossa breakage lever 45 to the thread-bail 40. In winding the package thestrand y draws through the groove 33 in the thread-guide 16 and thereciprocation of the guide causes the yarn to be traversedlongitudinally of the axis of the winding-spindle for the full length ofthe package to deposit it in helical coils which build up in layers toform the package.

The present improved reserve winding device is arranged in relation tothe above described mechanism as next explained. The reserve ,windingdevice is attachable to and supported upon the swinging traverse-frame1'7 by means of a twisted sheet-metal strip 46 constituting a bracket orstandard therefor. The end of the standard 46 is slotted at 47 toreceive one of the screws 48 which secure the back 37 to thetraverse-frame 17. The standard 46 is also formed with an upper slot 49which receives the shank of one of the screws 39 for the thread-bail 40.The slots 4'7 and 49 providefor adjusting the standard 46 onthe screws48 and 39 so that the reserve winding device may be positioned toproperly.

locate the first coils of yarn with respect to the end of the package tobe wound on the cop-tube C. After the device has been properly adjustedin position the screws 48 and-39 are tightened to rigidly attach thestandard 46 to the traverseframe 17 to position the yarn-controllingdevice in close proximity to the surface of the cop-tube C at its baseend thereof.

The present reserve winding device embodies an auxiliary guide oryarn-controller 52 which, as herein shown, is forked to provide a curvedfinger 53 and a shorter straight finger 54 between which is a V-shapedcrotch or guideway 56. The guideway 56 is adapted to receive the strand2/ which is maintained therein'in the position illustrated in Figs. 1and 3 at the commencement of the winding operation to provide forwinding the reserve length of yarn on the butt end of the cop-tube C.The yarn passes across the threadbail 40 and directly through theguideway 56 of the controller 52 to the cop-tube C. After the reservewinding is completed the controller 52 is automatically shifted into theposition illustrated by full lines in Fig. 4 and shown by dotted linesin Fig. 5. Through this operation the yarn, without leaving thethread-bail 40, is transferred from the guideway 56 of the controller 52to the groove 33 of the thread-guide 16 to be traversed during theensuing winding operation to build the package with a warp wind.

The controller 52 is constituted as a part of a rockable lever or member55 comprising bearing ears 5'7 and 59 connected by a lateral strip orcrossbar 58. Projecting from the opposite end of the crossbar 58 is afinger-piece or lever 61 which serves as a means for manually rockingthe member 55. The ears 5'7 and 59 are provided with alining holes, inwhich is held a rod 62 having its projecting ends journaled in bearingears 63 bent at right-angles to the twisted upper portion of the bracketor standard 46. The crossbar 58 of the member 55 is formed with anangular latch or detent-lug 64 adapted to pass through a slot 66 in ahorizontal plate or platform 6'7 forming a part of the standard 46 andto be engaged beneath the edge of a ratchet-disk 68 rotatable on theplatform. The disk 68 is provided with a radial slot or opening '70through which the detent-latch passes to release the member 55. Oppositethe lug 64 an integral stop-finger 69 projects from the side of thecrossbar 58 of the member 55. A spring '71 coiled around the horizontalpivot-rod 62 and made fast at its opposite ends to the stop-finger 69and the standard 46 tends to rock the member 55 upon the completion ofthe reserve winding and the release of its detent-latch 64 from underthe disk 68, whereby to alter the position of the yarn-controller 52 inthe manner and for the purpose as later explained. The rocking movementof the member 55 under the action of the spring 71 is limited bythe'contact of its stop-finger 69 with the end of a set-screw '72adjustable in the standard 46 to vary the extent of throw of theyarncontroller 52.

The ratchet-disk 68 is journaled on a fixed stud '73 projecting upwardlyfrom the platform 6'7 on the standard 46, the top of the disk beingcounterbored to accommodate a retaining flange '74 on the stud. The disk68 is controlled by a helical wind-up spring '76 coiled about the stud'73. One end of the spring '76 is engaged in a hole '77 in the disk 68and the other end held in a transverse slot '78 in the upper end of thestud 73, the tension of the spring tending to rotate the disk 68 in aclockwise direction as viewed in Figs. 6 and '7.

Secured fast to the upper reduced portion '79 of the disk 68 is anannular ratchet 81 having a series of peripheral teeth 82 extendingthroughout the greater portion of its circumference and terminating in aradial projection or stop-finger 83. The ratchet 81 is held fast on thedisk 68 by means of opposite screws 84 threaded into the disk withwashers 86 under their heads. The ratchet 81 projects slightly above thetop of the disk 68 to adapt the washers 86 to bind thereagainst to clampit fixedly to the disk. By loosening the screws 84'the ratchet 81 may beturned on the disk 68 to adjust the angular relation between thestop-finger 83 and the slot 70 whereby to regulate the timing of actionof the yarn-controller 52. The rockable member is released to permit theshifting of the controller 52 when the disk 68 has been rotated to aprescribed extent to bring its slot 70 into register with thedetent-latch 64.

Pivoted on a vertical stud 87 fastin the platform 67 is a lever 88formed with a pawl 89 at one end for progressively engaging the teeth 82of the ratchet 81 toprevent retrogressive movement of the disk 68 underthe action of its spring 76. A spring '90 connected at to an ear 91 inthe lever 88, and suitably at the other end to the standard 46,v urgesthe pawl 89 into engagement with the teeth '82. The lever 88 has arearwardly-extending farm v92 adapted to be operated'upon to release thepawl 89 from the ratchet in the manner and for the purpose as laterexplained. I

The ratchet-disk 68 is progressively rotated in a contraclockwisedirection, as viewed inFigs. 6 and 7, by means of a lever 93 carrying apawl 94 engageable with the teeth 82 of the ratchet 81.

The pawl 94 is of spring-metal riveted to the side of the lever 93 at 95and having a finger 96 at its upper end bent at right-angles to extendthrough a slot 97 in the end' of the lever. Projecting from one side ofthe pawl 94 is another finger 98 bent forwardly to adapt its end to beengaged by the curved finger 53 of the yarn-controller 52. Ihe lever 93is pivoted on a depending portion 99 of the platform 67 by means of astud 100 with the side of its lower arm engaged by the end of aleaf-spring 101. The spring 101 has a bent portion 102 overlying theforward side of the standard 46 and riveted thereto at 103, see Fig. 2.The lever 93 is rocked to turn the ratchet-disk 68 by the intermittentengagement of the thread-guide arm 31 with its lower end. As theratchet-disk 68 is progressively rotated in the manner indicated thepawl 89 engages with the teeth 82 to prevent its retrogressive movement.Upon the return movement of the lever 93 the springapawl 94 yields topermit its end to slide back across one tooth to engage with asucceeding tooth. A stop-finger 10.5 secured fast on the standard 46 bya screw 104 is positioned to lie in the path of the lever 93 to limitits return movement. By adjusting the finger 105 to raise or lower itsouter end the range of movement of the lever 93 may be regulatedto varythe extent of rotative movement of the ratchet-disk 68 under the actionof the pawl 94.

The lower end of the lever 93 carries a contact-element or bunter 106adapted to be engaged by the side of the thread-guide arm 31 at the endof each rearward stroke of the latter. The bunter 106 is secured fast onthe lever 93 by means of a screw 107 passing through a slot 108 therein.By loosening the screw 107 the bunter 106 may be adjusted on the lever93 to insure its proper contact with the guidearm 31 to effect actuationof the ratchet-disk 68.

The disk 68 is provided with a stop or pin 109 projecting from itsperiphery in position to engage against the side of the lever 93 afterthe disk has been turned to a position to cause action of theyarn-controller 52. The lever 93 is caused to make one more stroke afterturning the disk 68 to release the detent-latch 64 on the member 55,thereby turning the disk through the space of one tooth to bring the pin109 against the side of the lever to hold,the latter from .with screws39 and 48 already in place. bracket 46 is adjusted in position with theyammoving back into position to be forcibly engaged during the furtheroperation of the machine.

The post or stud 87 on the topof the standard 46 is formed with athreaded hole 112 for receiving a screw 113 by'means of which a cover orcasing 114 is attached to the device to enclose its operating mechanism.The top of the casing 114 is provided with an aperture to receive thestud 73 whereby the casing is arranged to closely overlie the mechanismenclosed therein. The method'of operation of the complete machine is asnext explained in detail.

As hereinbefore noted, the reserve winding device or yarn-control unitmay be attached to standard types of winding machines to cooperate withthe traversing means thereof without alteration in the mechanism of themachine. lhe

device maybe mounted on the swinging traverseframe of the machine byattaching it thereto The controller 52 located with its crotch orguideway 56 at a point opposite the base end of the coptube C, justoutsidethe zone of traverse of the thread-guide 16. To prepare themachine for winding thecop-tube C is placed on its mandrel or holder 5and secured thereto by suitable means as usually provided. With thethread-controller 52 held in initial position by the engagement of itsdetent-latch '64 inunder'the edge of the ratchet-disk 68 the machine isthreaded up in the manner as next explained. I

The strand 3/ of yarn, thread or the like is drawn up from its source ofsupply through the tension-device 43 and slub-catcher 44, thence acrossthe breakage lever, 45 and led over the thread-bail 40. The end of thestrand is passed through the guideway or crotch 56 in the yarncontroller52 and attachedto the cop-tubeC in any suitable manner as usuallyemployed. Before, starting the machine to operate the traverse-frame 17is swung back into erect position with the thread-guide 16 bearingagainst the surface of the cop-tube Cin the manner as indicated in Fig.2 of the drawings.

The machine is started to operate by throwing the starting lever toconnect the driving pulley 6 with the clutch 7 which is fast on thewindingspindle 3. The spindle 3 is thus caused to be driven to rotatethe cop-tube C to wind the strand thereon as it feeds across thethread-bail 40 and through the yarn-controller 52. Concurrently with therotation of the winding-spindle 3 the traverse-rod 27 is reciprocated bythe cam 14 to cause the thread-guide 16 to traverse backv and forthlongitudinally of the axis of the coptube C. I

During the initial stages of the operation of the machine theyarn-controller 52 remains fixed in the position shown in Figs. 1 and 3with the strand y drawing across the top of the threadbail 40 as shownmost clearly in Fig. 3 and leading through the crotch 56 in thecontroller to cause it to be coiled about the base end of the cop-tube Cwithout traversing it thereon. The strand 1; feeds from the thread-bail40 through the yarn-controller 52 and thence directly to the surface ofthe cop-tube C as it draws downwardly from the controller in tangentrelation to the periphery of the tube, see Fig. 2. That portion of thestrand drawing down from the controller to wind about the base end ofthe cop-tube C is beyond the range of traverse of the thread-guide 16,as will be apparent by reference to Fig. 3. Fig. 3 shows the threadguide16 at the extreme end of its inward traverse or, more specifically, atthe limit of its traverse in the right-hand direction, and the yarndrawing through the controller 52 feeds to the surface of the cop-tube Cat a point outside the range of the thread-guide to prevent the strandfrom entering the slot or groove 33 in the guide. The yarn will thus becaused to make a number of turns 11 about the base end of the cop-tube Cto provide a reserve length for splicing to another cop in a series; thenumber of turns in, or the length of, this reserve winding beingdetermined by the setting of the control device.

Referring to Figs. 6, 7 and 8, it has been explained that the ratchet 81is adjustable rotatively on the disk 68 and by regulating the positionof the stop-finger 83 with reference to the release slot '70 in the diskthe device may be set to release the yarn-controller after any desirednumber of strokes of the thread-guide 16. That is to say, the positionof the stop-finger 83 with respect to the release slot '70 in the disk68 determines the extent to which the disk must be moved intermittentlyby the action of the pawl 94 on the lever 93. It will be understood thatthe winding-spindle makes several revolutions during one completetraverse of the thread-guide and for the purpose of the presentexplanation it may be considered that the cop-tube C is revolved sixtimes to one movement of the thread-guide 16 from the inward extreme ofits traverse outwardly and back again. As illustrated in Fig. '7 of thepresent drawings the ratchet 81 is adjusted on the disk 68 in suchposition that it requires the disk to be turned through the space ofseven teeth to carry the slot 70 in the disk into position to releasethe detentlatch 64 on the controller-member 55. Consequently, with suchan adjustment of the device the cop-tube will make six times seven orfortytwo revolutions before the controller is released so that forty-twocoils or turns of the yarn will be wound onto the base of the cop-tubeto provide the reserve length.

As the initial reserve winding operation proceeds the thread-guide arm31 is caused to make contact with the hunter 106 on the lower end of thelever 93 at the end of each rearward stroke of the thread-guide. As thethread-guide arm 31 moves away from the bunter 106 on the forwardtraverse the spring 101 rocks the lever 93 to slide its pawl 94rearwardly on the ratchet 81 to engage a succeeding tooth thereof. Atthe next rearward traverse movement of the thread-guide its arm 31 willagain rock the lever 93 to advance the ratchet in the same manner, andin this way the disk 68 is intermittently rotated until its slot oropening 70 is turned to a position in register with the opening 66 inthe shelf 6'7.

At this juncture the detent-latch 64 is released to swing through theopening 70 in the disk 68 as the member 55 is rocked by its spring '71.The member 55 is rocked downwardly until its stopfinger 69 contacts withthe end of the stop-screw '72 and the control-member 52 is thus shiftedfrom its initial position as illustrated in Fig. 3 to the down positionas shown in Fig. 4. As the controller 52 is rocked on its pivot thestrand y held therein is released from its crotch or guideway 56 in themanner as illustrated in Fig. 4. Upon its release the strand y will bedrawn directly from the thread-bail 40 to the surface of the cop-tube Cand will assume a position as indicated by the dotted line in Fig. 4.Now, as the threadguide 16 approaches the inward end of its trav-' erseits convex face will ride over the length of yarn y and cause it to bepicked up in the groove or slot 33 of the guide. Immediately the guidepicks up the yarn in this manner it is traversed thereby back and forthalong the length of the cop-tube C to build the cop, cone or other formof package with a warp wind, the yarn being laid in helical turnscrossing and recrossing each other to form overlying layers constitutingthe body of the package.

The operation of the winding machine continues until the package hasreached the desired size, whereupon the machine is stopped, usuallythrough the intermediary of sizing mechanism, so-called, as generallyprovided on machines of the present type. The full package is dottedfrom the cop-holder 5 and the machine prepared for winding anotherpackage in the same manner as hereinabove described. To set the reservewinding device to operate during the initial stages of the winding itonly is necessary to swing the control-member 55 back into position toengage its detent-latch 64 in under the disk 68. This operation isperformed by placing the finger upon the lever 61 to swing the member 55upwardly to restore the detent-latch in detained position under the disk68.

During this operation the finger-lever 61 engages against the rearwardend of the arm 92 of the lever 88 to swing the latter to release itspawl 89 from the ratchet 81. The manual operation of the member 55further causes the curved arm 53 on the controller 52 to engage againstthe finger 98 on the spring-pawl 94 whereby to release the latter fromthe ratchet 81. In this manner the ratchet is freed to .permit thespring '76 to return the disk 68 to its initial position with the radialstop-finger 83 bringing up against the side of the lever 93 as shown inFig. 6. Upon the release of the finger-lever 61 the pawls 89 and 94 areagain returned into engagement with the ratchet and the device is readyfor another cycle of operations.

It will be observed from the foregoing that the present inventionprovides a simple and efficient device for effecting the winding of areserve length of yarn on the cop-tube or other support before thecommencement of the winding of the package.

The device can be adjusted to secure any desired length of yarn in thereserve winding in accordance with requirements and when once adjustedwill operate repeatedly at the start of each package. The setting of thedevice merely requires the movement of a single element and the meanswhich controls the yarn to wind a reserve length on the cop-tube isconvenient and easy to thread with the same motion of the hand asordinarily required in preparing the machine to operate without thereserve winding.

The reserve winding device is universally applicable to various types ofwinding machines without alteration in construction or arrangement ofthe mechanism thereof. -Moreover it can be readily attached and adjustedin position and is compact in size, efiicient in operation and notliable to breakage or getting out of order.

While the device is herein described and illustrated as embodied in apreferred form of construction, it is to be understood thatmodifications may be made in the structure and arrangement of itsmechanism and in the method of adapting it to winding machines of othertypes than that herein shown, without departing from the spirit andscope of the invention.
